Hi, The other day I turned on my MacBook (only 2 months old) and I couldn't connect to my wireless router. It's a DLink G604T with updated firmware, WPA encryption, and works fine with all the Windows PC in my home. I now get the standard "cannot connect to..." error each time I try to connect to the network, either with WEP or WPA. No encryption, and I can connect no problem at all. The previous day I'd installed Apple's 2007-002 update. Apple suggested reinstalling the OS and not installing that update. This had exactly no effect whatsoever. I've also tried resetting the router to default settings and starting over, different passwords, different channels. So, it's not the router (works with PCs), it's not the OS (reinstalled), it's not the hardware (works without WEP and WPA)... I'm completely at a loss... Does anyone have any idea what the problem might be?
